And obtained product
Technical field
The present invention relates to building ceramics technical field, more particularly to a kind of architectural pottery glaze and glaze layer preparation
Method and obtained product, it is adaptable to have ceramic wall and floor bricks and square brick of high abrasion demand etc..
Background technology
With the fast development of domestic real estate market in recent ten years, China's architectural pottery industry obtains unprecedented
Opportunity to develop, however as the renewal of the new decoration technique application of architectural pottery and product type, glaze paint wearability is poor to ask
Topic is increasingly becoming the bottleneck that restriction architectural pottery further develops, and the wear-resisting series of current overwhelming majority glaze paint brick product is 4
Level, it is difficult to reach 5 grades, the appearance of particularly high-end Full-glazed tile and crystallite brick product exacerbates architectural pottery industry resistance to height
The pressing needs of glaze are ground, therefore the wear-resisting sex chromosome mosaicism of glaze paint has caused the extensive concern of domestic and international ceramic material industry.
At present, its wearability is improved by improving hardness of glaze surface has turned into the common recognition of industry, and prior art is mainly logical
The crosslinking degree for increasing glaze layer glass structure is crossed, the raising of hardness of glaze surface and mechanical endurance is realized.For example, by glaze
Ultra-fine corundum powder is introduced, to improve the content of aluminum oxide in glaze, due to [AlO4] and [SiO4] it is collectively forming glass network knot
Structure, increased the crosslinking degree of structure, thus improve the wearability of glaze paint to a certain extent.However, in actual applications
It was found that, although aluminum oxide can increase hardness of glaze surface, the glossiness of glaze paint can be also reduced simultaneously and increases glaze paint water ripples.This
Because enamel needs to realize that vitrifying is flowed at 1200 DEG C or so, to be formed and the close binder of base substrate and obtain good
Surface property, which has limited the amplitude that network structure crosslinking degree in glass frit is improved, because the degree of cross linking high will cause
Glass frit softening temperature is significantly improved with flowing temperature.
Further to improve the wearability of glaze paint, the new think of as glaze using glass ceramics frit is it is also proposed at present
Road, i.e., processed by carrying out controlled micro crystallization to glaze paint, significantly improves the hardness of glaze paint.However, the growth course of crystallite is difficult to control
Make, and crystal is easily grown up in high temperature environments, and thick crystal not only influences glaze layer optical property, and it is easily caused glaze
The deterioration of face mechanical performance.Therefore, how optimisation technique so that a large amount of particles are generated in glaze layer during ceramic firing tiny
Micro crystal, be improve architectural pottery glaze paint wearability key.
